FirebaseUI Email starts the Email sign in flow at startup

I'm having trouble with the FirebaseUI. The problem is, is that it starts the Email sign in flow at startup without clicking on anything. I want it to show the different sign in options, but it keeps starting the email sign in flow. I want it to show this:

But instead it goes directly into the email sign in flow whenever the app starts and without clicking anything. I never get the option to choose Facebook nor Google

This is my LoginActivty

public class LoginActivity extends AppCompatActivity {

private static final int MY_REQUEST_CODE = 7117;
private FirebaseAuth mAuth;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    mAuth = FirebaseAuth.getInstance();
    setContentView(R.layout.activity_login);
    showSignInOptions();
}

@Override
protected void onStart() {
    super.onStart();
    FirebaseUser currentUser = mAuth.getCurrentUser();
    if (currentUser != null) {
        startActivity(new Intent(LoginActivity.this, MainActivity.class));
    }
    else {
        Toast.makeText(this, "", Toast.LENGTH_SHORT).show();
    }
}

public void showSignInOptions() {
    AuthMethodPickerLayout loginLayout = new AuthMethodPickerLayout
            .Builder(R.layout.activity_login)
            .setEmailButtonId(R.id.email_button)
            .setFacebookButtonId(R.id.facebook_button)
            .setGoogleButtonId(R.id.google_button)
            .build();
    startActivityForResult(
            AuthUI.getInstance().createSignInIntentBuilder()
                    .setTheme(R.style.AppTheme)
                    .setAuthMethodPickerLayout(loginLayout)
                    .build(), MY_REQUEST_CODE
    );
}

@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (requestCode == MY_REQUEST_CODE) {
        IdpResponse response = IdpResponse.fromResultIntent(data);
        if (resultCode == RESULT_OK) {
            startActivity(new Intent(LoginActivity.this, MainActivity.class));
            FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
            Toast.makeText(this, "Welcome " + user.getDisplayName(), Toast.LENGTH_SHORT).show();
        }
        else {
            Toast.makeText(this, "" + response.getError().getMessage(), Toast.LENGTH_SHORT).show();
        }
    }
}

I don't see anywhere in my code that says it should start the emailflow. Please help me. Thanks in advance

Fixed it. All I needed was to use

setAvailableProviders();

For my SignInIntentBuilder();

Code for my new LoginActivity:

public class LoginActivity extends AppCompatActivity {

private static final int MY_REQUEST_CODE = 7117;
private FirebaseAuth mAuth;

@Override
protected void onStart(){
    super.onStart();

    FirebaseUser currentUser = mAuth.getCurrentUser();
    if (currentUser != null) {
        startActivity(new Intent(LoginActivity.this, MainActivity.class));
        Toast.makeText(this, "Welcome back " + currentUser.getDisplayName(), Toast.LENGTH_SHORT).show();
    }
    else {
        Toast.makeText(this, "Please log in", Toast.LENGTH_SHORT).show();
    }
}

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_login);
    mAuth = FirebaseAuth.getInstance();

    showSignInOptions();
}

private void showSignInOptions() {
    List<AuthUI.IdpConfig> providers = new ArrayList<>();
    providers.add(new AuthUI.IdpConfig.EmailBuilder().build());
    providers.add(new AuthUI.IdpConfig.FacebookBuilder().build());
    providers.add(new AuthUI.IdpConfig.GoogleBuilder().build());

    AuthUI.SignInIntentBuilder builder = AuthUI.getInstance().createSignInIntentBuilder();
    AuthMethodPickerLayout loginLayout = new AuthMethodPickerLayout
            .Builder(R.layout.activity_login)
            .setEmailButtonId(R.id.email_button)
            .setFacebookButtonId(R.id.facebook_button)
            .setGoogleButtonId(R.id.google_button)
            .build();

    startActivityForResult(
            builder.setAuthMethodPickerLayout(loginLayout)
                    .setAvailableProviders(providers)
                    .setTheme(R.style.AppTheme)
                    .setIsSmartLockEnabled(false)
                    .build(), MY_REQUEST_CODE);
}

@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (requestCode == MY_REQUEST_CODE) {
        IdpResponse response = IdpResponse.fromResultIntent(data);
        if (resultCode == RESULT_OK) {
            FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
            Toast.makeText(this, "Welcome " + user.getDisplayName(), Toast.LENGTH_SHORT).show();
        }
        else {
            Toast.makeText(this, "" + response.getError().getMessage(), Toast.LENGTH_SHORT).show();
        }
    }
}

This is the code that starts the sign-in flow:

startActivityForResult(
    AuthUI.getInstance().createSignInIntentBuilder()
        .setTheme(R.style.AppTheme)
        .setAuthMethodPickerLayout(loginLayout)
        .build(), MY_REQUEST_CODE
);

startActivityForResult does exactly what it says - it starts an activity, and in this case, it's being told to start the Firebase UI activity. Since you're calling it during onCreate, the current activity will never be visible to the user.
